3M Soft disc for feet 125mm diameter #400 50 pieces

The abrasive grains were deeply embedded in the base material and firmly fixed by adhering with a high-strength epoxy adhesive. Even after polishing for a certain period of time, the abrasive grains do not wobble with respect to the base material and are firmly fixed, so the force can be efficiently transmitted to the polished surface. Due to this characteristic, we have achieved overwhelming "mochiness" that is 1.5 to 2 times that of general products, especially in machine sharpening with high polishing speed. Since the heights of the abrasive grains are aligned and arranged densely, the touch feel is less likely to get caught on the polished surface, and the polishing power seems to be low. When you actually polish it with mechanical sharpening, you can feel the certain "goodness". A 125 μm (micron) urethane film is used to achieve €œsoftness€ and high durability, which are ideal for the footing process. Since the soft base material has high followability to curved surfaces, footing work can be performed efficiently. Not only is this base material soft, but it also has a certain thickness and "stiffness", so it is easy to fold it in four and polish finely intricate parts, for example. In addition, the thickness and durability of the base material have been sufficiently ensured so that the perforations will not get caught and torn when the sheet is polished in full size.
